One of the nice things I find about living in the US over the years is having access to a variety of food. I’ve mentioned this in previous posts but I was limited in terms of what food was available in Romania. An example of that food is the humble sweet potato. I now more than make up for the lost years by eating a plethora of them. I use sweet potatoes in soups, curries, simply roasted, baked, fried, etc. They’re versatile and delicious.

And this sweet potatoes and kale recipe with caramelized onions are a delicious and easy 3 ingredient side or even entree. You can simply make the sweet potato sautee and throw in avocado and a fried egg and call that a pretty fantastic healthy lunch or dinner.

It's nutritious, paleo, vegan, whole30 and so simple to make. #calmeats, #vegan, #sweetpotato, #whole30, #paleo, #kale, #sidedishes, #vegansides, #paleosides, #whole30sides #thanksgiving #fallerecipes #autumnrecipes #veganrecipes #sweetpotatoes

Tips For Making Sweet Potatoes With Kale And Caramelized Onions

Look For Organic Sweet Potatoes

Because we’re talking about only three ingredients, it’s important that you source the best possible sweet potatoes, kale, and onion.

I highly recommend using the freshest organic sweet potatoes for this dish because the sweet potatoes will be the star of the dish and you want the sweetest, freshest sweet potatoes available. Farmers’ markets are usually the best place to find them but fresh organic at your local market will work perfectly fine.

What Is The Best Kale To Use?

You could use red kale or Lacinato kale but find green kale to hold up best in this dish. Also, I recommend getting the freshest organic kale as well, with sturdy vibrant, green leaves that will hold up well in cooking.

Yellow Or Sweet Onion?

That’s entirely up to you. I lean towards sweet onion often when making this dish but I’ve made it numerous times with yellow onion. The trick is to let the onion cook low and slow until all the natural sugars are released and the onion starts to caramelize. It’s tempting to want to rush it, but you’ll get a distinct melt-in-your-mouth sweet onion in every single bite.

What To Serve With Sweet Potato And Kale Sautee?

This dish works really well with meat, chicken, pork, and salmon. It’s also perfect with tempeh or tofu, hearty mushrooms, or any other variation you’d like.

Another idea is serving the sweet potato kale combination in a salad. It’s always a good idea.

How Do You Store Leftovers?

This sweet potato sautee will store in the refrigerator for 2-3 days. I often use the leftovers for lunches or dinner the next day and top them with an over-easy egg. Sweet potatoes and eggs work well together.

    Oh my gosh, I made this recipe with added spinach, avocado, an sliced apple, slice almonds, not a salad though, I just added these ingredients to the stove top with the other ingredients then at the end I added boiled eggs to this mixture. I must say very tasty and I enjoyed all these ingredients together. I ate like this for a month and lose 12 pounds too. Superfood eaten altogether, nice.
